After a supernova, the stellar core may remain as a neutron star or, for more massive stars, collapse into a black hole. Neutron stars are extremely dense, composed almost entirely of neutrons, while black holes have such strong gravity that not even light can escape from them.
What else can I help you with?
How much does a supernova weigh?
A supernova itself doesn't have a specific weight as it is not a single object but rather a stellar explosion marking the end of a star's life cycle. The mass involved in a supernova can vary widely, often between 1.4 to several tens of solar masses (the mass of our Sun). During the explosion, a significant portion of the star's mass is ejected into space, while the remnant core may collapse into a neutron star or black hole.
In the last stage of stellar evolution following a supernova stars too massive to form neutron stars may form a?
In the last stage of stellar evolution, stars too massive to form neutron stars may collapse into black holes following a supernova explosion. When these massive stars exhaust their nuclear fuel, their cores collapse under gravity, leading to an event horizon that characterizes a black hole. The outer layers are expelled during the supernova, while the core's collapse results in an incredibly dense singularity from which nothing, not even light, can escape. This process marks the end of the star's life cycle, transitioning it into a black hole.
A what is produced when the outer core of a star explodes after the core collapses?
The process of the stellar explosion is called a "nova", or if powerful enough, a "supernova". The outer layers of gas are blown away into space, and this shell of fleeing gas is sometimes called a "supernova remnant", or more generally, a "nebula". For example, the Crab Nebula is the gas cloud left over after a supernova explosion which was brilliantly visible here on Earth in the year 1054.
What determines which stage occures after a supernova?
No one knows for sure, since there is not enough information to figure it out. After a supernova, the star will either turn into a black hole, a neutron star, or a pulsar. But, there is no scientific evidence that proves which one the star will turn into after a supernova.
Which element in the core of a high mass star leads ultimately to a supernova explosion?
The Answer may be hydrogen. Hydrogen moves to the suns core as it starts to die, or explode. hydrogen is a very flammable gas. A star, like the sun is surrounded by heat. this heat will ignite the hydrogen gases as it moves to the core. This ignition of the hydrogen will cause the star to expand in size and increase in temperature.

Are there planets orbiting suppernovas?
No. A supernova is star that is exploding. If any planets are orbiting a star that explodes, they will be destroyed. There is evidence that after a supernova new planets may form from the debris cloud left behind and orbit the stellar remnant, which will be either a neutron star or a black hole depending on the mass of the star that exploded..

If the core of a supernova contains about one solar mass the core will become a .?
If the core of a supernova contains about one solar mass, it will likely become a neutron star. This dense remnant forms when the core collapses under gravity, causing protons and electrons to combine into neutrons. Neutron stars are incredibly dense, with a mass greater than the Sun compressed into a sphere only about 20 kilometers in diameter. If the core exceeds around three solar masses, it may collapse further into a black hole.
What is the remains of a star called after a supernova?
The remains of a star after a supernova can be classified primarily as either a neutron star or a black hole, depending on the mass of the original star. If the core's mass is below a certain threshold, it may collapse into a neutron star, which is incredibly dense and composed mostly of neutrons. If the core's mass exceeds this limit, it may collapse further into a black hole, where gravity is so strong that not even light can escape. Additionally, the explosion disperses the outer layers of the star into space, creating a supernova remnant.
What element is usually the remnant of a supernova?
The remnant of a supernova is typically composed of elements such as iron and nickel, which are formed during the star's life cycle. After the supernova explosion, these elements can be dispersed into space, contributing to the formation of new stars and planets. Additionally, neutron stars or black holes may form from the core remnants of very massive stars.
What type of stars hotter?
The hottest stars are supernova explosions, which may reach temperatures around a billion kelvin in the star's core.
What if left behind after a star with four or more stellar masses has died?
When a star with four or more solar masses exhausts its nuclear fuel, it undergoes a supernova explosion, leaving behind a dense core. This remnant can become a neutron star if the core's mass is below about three solar masses, or it may collapse into a black hole if it exceeds that limit. The explosion disperses the outer layers into space, enriching the surrounding medium with heavy elements forged during the star's life and explosive death.
What happens to a massive star when its fusion period is over?
Once a star's nuclear fusion has ended, it will collapse inside its core and become what is known as a white dwarf. Its outer layers will shoot out into the universe as planet nebula. If they are very large, stars will explode into a Supernova and their core will collapse into a black hole.
